Trilacuna rastrum Tong & Li, 2007

Diagnosis.

Trilacuna differs from other oonopid genera, except those of the " Dysderoides complex" (including Bannana Tong & Li, 2015, Dysderoides Fage, 1946, Himalayana Grismado, 2014, and Trilacuna), by the enlarged male palpal femur, the very complex embolus-conductor system, and the notched labium. Males differ from the other genera of the " Dysderoides complex" by usually lacking the furrow connecting the posterior tracheal spiracles, and females differ by having a long postgastric scutum covering almost the whole ventral abdomen (Grismado et al. 2014; Tong et al. 2019).

Composition.
